Remote sensor SPI register map

The Remote Sensor SPI interface consists of twelve 32-bit read registers (one for each

logical channel) to allow for access to decoded sensor data and fault registers. The registers

are addressed by the read register ID and the Global ID bit.

The L9680 checks the validity of the received RID field in the MOSI_RS frame. Should a SPI

read command be received containing an unused RID address, the command will be

discarded and the ERR_RID bit will be flagged in the current GSW.
